STAMPING DEVICE.

SPECIFICATION forming part of Letters Patent No. 784,638, dated March 14, 1905.

Application filed December 9, 1903. Serial No. 184,504.

To all whom it may concern.-

Be it known that 1, JOHN N. STEWART, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Stamping Devices, of which thefollowing isa specification.

My invention relates to improvements in stamps of the class in which a pivoted support for the type-carrying roller is mounted above I the table or pad, so that a blow fromthe hand or other pressure will bring said roller into contact with the paper or other material interposed between it and the pad, thereby impressing upon the paper any desired inscription.

My stamp is designed especially for the use of banks or other business ofiices for stamping or inscribing any desired matter upon checks or other business papers.

The special objects of my invention are to provide a compact stamp, simple and light in construction, easily kept in order, and thoroughly efficient for all the purposes and uses of such an article.

In the accompanying drawings, Figure 1 is a general perspective outside view of my stamp. Fig. 2 is a central vertical cross-section through the stamp. Fig. 3 is a perspective View of the type-roller detached, on a somewhat enlarged scale. Fig. 4. represents an operating or indicator wheel or nut mounted on the end of the type-roller shaft. Fig. 5 is a perspective View of the sectional ink-roller detached, on the same scale as Fig. 3. Fig. 6 represents one of the sections of the ink-roller. Fig. 7 is a detached perspective view of the spring-hook device for supporting the ink-roller.

1 indicates the metal base or table, which may be provided at the proper point under the type-roller with a suitable pad, composed of cork, rubber, or other elastic material, upon which the paper or other article to be stamped may be placed to receive the impact of the stamp. The shell, casing, or frame 2 is hinged to lugs or standards 3, extending upward from the base 1. Said shell 2 is hinged or suspended over the base 1 in such a manner as to allow any desired degree of play and admitting of a sufiicient opening between the shell 2 and base or pad 1 to permit the insertion of the article to be stamped. A suitable means of so suspending the shell is shown in Fig. 2, consisting of a spring 4; inserted between the base and shell, its ends resting in notches in those parts. Said shell, as shown, is substantially in the form of a half-cylinder closed at both ends, 'in which end sections is mounted the shaft 5 of the type-roller 6. Said type-roller extends slightly below the shell 2 and is provided on its cylindrical surface with aseries of suitable inscriptions in letters, figures, or otherwise arranged longitudinally, which inscriptions may be made fixed or removable and changeable in any desired manner. Said inscriptions are usually arranged at such distances apart that only one line will be impressed upon the paper at each opera,

tion of the stamp.

On the outer end of shaft 5 is mounted the operating and indicator wheel 7, of bone, metal, wood, rubber, or other preferred material, and provided on its curved surface with a series of abbreviations or symbols corresponding with or indicative of the inscriptions on the type-roller. For greater convenience saidabbreviations are preferably arranged so as to appear at some predetermined point on the indicator 7 easily visible to the operator at the same time that the corresponding inscription on the type-roller is under said roller in position tobe impressed on the paper.

The ink-roller 8 is composed of a series of separable cylindrical sections ordisks all mounted movably on a shaft 10. Said sections are composed of any suitable porous material, such as felt, adapted to absorb andretain theink and deliver the same to the ty pe-roller 5 when brought in contact therewith. The object in making the ink-roller insection's is that said sections may be easily separated from each other on the shaft 9 or removed entirely therefrom, so that not only their surfaces but also their sides and interiors (through the shaft-open ings) may be thoroughly inked and may absorb the ink, after which said sections may again be assembled compactly on shaft 9, and they will deliver an even supply of ink to the surface of the composite roller and deliver the I may be made Without departing from the essensame evenly to the faces of the inscriptions on roller 6. A reserve supply of ink is thus furnished to the ink-roller, so that it will remain serviceable much longer than if ink were merely applied to its surface in the ordinary way.

The ink-roller is supported in position to contact with the type-roller 6 by means of spring-hooks 11 11, mounted rigidly on the outer ends of arotatable cross-rod 12, extending through the shell 2. Said hooks engage with their concaved ends the outer ends of shaft 10 of the ink-roller, thus forming bearings for said shaft. The end walls of the shell 2 contain slots or recesses 16, so formed that their edges also serve as a part of the bearing for shaft 10, said shaft being supported from below or outwardly by thehooks 1111, its upward movement restricted by contact with the edges of slot 16 and supported on the side toward type-roller 6 by the constant contact of the ink-roller 8 with said type-roller. Said hooks 11 11 are kept in engagement with shaft 10, pressing the ink-roller constantly toward the type-roller by means of a spring 13, secured at each end to red 12,c0iled around said rod and having a central loop or projection 1% bearing against the inside of shell 2. It will be seen that the ink-roller10 while fully supported and retained in operative position is also free to yield to the pressure coming from type-roller 6 in the rotation of thelatter, such prssu re being exerted whenever one of the raised inscriptions on the type-roller passes the ink-roller.

sure upon the spring-hook device may be exerted, preferably,by means of a pressure plate or lever 15, Fig. 7, on one of said hooks.

it is obvious that slight changes in construction from that shown in the drawings tial features of my invention as set out in the claims. For example, the pivotal points of the hooks 11 l1 maybe changed or the form of the recess or slot 16 modified without affecting the operation.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a stamping device, a base, a springsupported shell pivoted thereon, a typeroller mounted in said pivoted shell, an ink-roller parallel with and driven by said type-roller, and spring-pressed pivoted hooks on the ends of said shell, supporting the ink-roller shaft and pressing it continuously toward the typeroller, substantially asset forth.

2. In a stamp, a base, a spring-supported frame pivoted thereon, a type-roller mounted in said frame, an ink-roller driven by said typeroller, a cross-rod rotatably mounted in the frame,hooks rigidly connected with said crossrod and engaging the ink-roller shaft, and a spring bearing on said cross-rod and pressing said ink-roller continuously toward the typeroller, substantially as set forth.

3. .In a stamping device, a base, a springsupported shell pivoted thereto and having slotted end walls, a type-roller mounted in said end walls, an ink-roller parallel with and driven by said type-roller and having its shaft extending through said slots, and springpressed pivoted hooks on the ends of said shell bearing against said shaft and supporting it in said slots, substantially as set forth.

4. In a stamp, a base, a spring-supported inclosed shell pivoted thereto and having slotted end walls, a type-roller mounted in said end walls, an ink-roller driven by said typeroller and having its shaft extending through said slots, and spring-pressed pivoted hooks supporting said shaft in said slots and pressing the ink-roller toward the type-roller, substantially as set forth.
